IKA LR 1000 basic Modular Laboratory Reactor System

Overview

The IKA LR 1000 basic is a modular, benchtop-scale jacketed glass reactor system engineered for precision-controlled chemical synthesis, process development, and multi-step reaction monitoring under reproducible thermal and mechanical conditions. Built on Couette-type mixing principles with bottom-heated thermal management, it enables accurate temperature regulation of reaction media via external heating mantles or circulating thermostats connected through its double-jacketed borosilicate glass vessel (Duran® 3.3). Designed for applications requiring moderate pressure tolerance (up to 1 bar gauge) and vacuum operation (down to 25 mbar), the system supports exothermic/endothermic reaction profiling, solvent reflux, crystallization, and controlled dispersion—particularly relevant in pharmaceutical process validation, cosmetic formulation R&D, and fine chemical synthesis where material compatibility and traceability are critical.

Key Features

• Modular architecture with standardized NS 29/14 ground-glass joints (1× NS 29, 3× NS 14) enabling seamless integration with condensers, dropping funnels, gas inlets, pH probes, or inline sensors
• Digital PID temperature control with integrated PT100.5 sensor (included) and ±0.2 K accuracy; optional external PT100 input support for multi-point thermal mapping
• Motor-driven anchor or paddle stirrer (standard); PTFE-coated anchor agitator available as accessory for high-viscosity or shear-sensitive media
• Intelligent safety logic: automatic shutdown upon lid removal, vessel displacement from heating base, or thermal runaway detection via dual independent safety circuits
• Adjustable overtemperature protection (50–210 °C range), real-time LED status indicators for heating, stirring, and safety states
• Rugged mechanical design featuring AISI 316L stainless steel housing, chemical-resistant PTFE/FKM seals, and IP21-rated electrical enclosure compliant with DIN EN 60529
• RS232 and USB interfaces for instrument parameter logging, remote operation, and audit-trail generation in GLP/GMP environments

Sample Compatibility & Compliance

The LR 1000 basic accommodates liquid, slurry, and semi-solid reaction mixtures up to 100,000 mPa·s viscosity. Its all-glass (Duran® 3.3) contact surface ensures inertness toward acids, bases, and organic solvents—validated per ISO 3585 and ASTM E438 Type I Class A specifications. The system meets essential requirements of EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. While not intrinsically rated for explosion-proof use, it may be operated in classified zones when paired with certified external spark-proof peripherals. Documentation includes full Declaration of Conformity, CE marking, and material compliance statements (RoHS, REACH).

Software & Data Management

Native communication via RS232 or USB allows direct integration into laboratory information management systems (LIMS) or electronic lab notebooks (ELN). IKA Labworld software (optional) provides time-stamped parameter recording—including speed, temperature setpoint/actual, safety events, and runtime—with export capability to CSV or PDF. All digital interactions comply with ALCOA+ data integrity principles. Audit trails include user ID, timestamp, parameter change history, and reason-for-change fields—supporting FDA 21 CFR Part 11 readiness when deployed with validated access controls and electronic signatures.

Applications

• API intermediate synthesis under controlled thermal profiles (e.g., Grignard additions, hydrogenations, esterifications)
• Emulsion and suspension development in topical pharmaceuticals and cosmeceuticals
• Crystallization kinetics studies with in-situ temperature ramping and seeding protocols
• Viscosity-dependent reaction monitoring (e.g., polymerization onset, crosslinking progression)
• Process scale-down validation for transfer from pilot-plant reactors to manufacturing lines
• Teaching laboratories for unit operations involving heat/mass transfer, agitation efficiency, and reaction calorimetry fundamentals

FAQ

Is the LR 1000 basic suitable for reactions under inert atmosphere?
Yes—NS-ground glass joints permit secure connection to Schlenk lines or nitrogen/vacuum manifolds using standard adapters.

Can external cooling be applied directly to the jacket?
Yes—the double-jacket design accepts circulating coolant (minimum inlet temperature 3 °C; max. pressure 1 bar) for active exotherm management.

What is the minimum recommended fill volume for reliable temperature control?
500 mL is specified to ensure adequate thermal mass and uniform heat distribution across the vessel base and sidewalls.

Does the system support regulatory-compliant data archiving?
When used with IKA Labworld and configured per site-specific validation protocols, it fulfills core data integrity expectations for GxP environments.

Is ULTRA-TURRAX® T25 dispersion tool integration supported out-of-the-box?
Yes—via optional mounting bracket LR 1000.61 and compatible drive interface; requires separate purchase of T25 unit and probe.
